Hi Bill,
The `org-confirm-babel-evaluate' variable can be set to a function which
can query the user to confirm code block evaluation. The following code
does two things.
1) it creates and maintains a list of the files that the user has said
are safe for evaluation (this list will need to be rebuilt every time
you re-start Emacs)
2) it shows the language and body of the code block to the user when
querying for evaluation
--8<---------------cut here---------------start------------->8---
(setq babel-safe-files '())
(defun my-babel-confirmation (lang body)
(let ((file (buffer-file-name)))
(if (member file babel-safe-files)
nil
(if (y-or-n-p
(format
(concat "#+begin_src %s\n%s#+end_src\n"
"Evaluate this code block "
"(and all others in this file) "
"on your system? ") lang body))
(prog1 nil
(setq babel-safe-files (cons file babel-safe-files)))
t))))
(setq org-confirm-babel-evaluate #'my-babel-confirmation)
--8<---------------cut here---------------end--------------->8---
This above can be added to your configuration to get close to the
functionality you describe.
I agree that the default confirmation should show the code block in
question when asking if it should be evaluated. I'll add this to our
development task list.
Note: the above requires that you pull down the latest version of
Org-mode.
